At least you recognise that it's most important to keep people safe, not everyone does. It's not good to be driving and accidentally mount kerbs n stuff - not that I've ever done that
I always have to make a judgement call but am glad that I can still drive most of the time. I had to switch to an automatic though because it's not easy to change gears when your clutch leg is constantly spasming!
Do you qualify for motability? It would make getting hand controls easier.
